Abstract

<P>PROBLEM TO BE SOLVED: To smoothly open and close a slide door and to make a door flat in the closed state even in a slide door with a simpler mechanism. <P>SOLUTION: A slide rail 2 includes a linear regulating wall B and two curved regulating walls A connected to both ends of the wall. In the slider 3, the link member is so constructed that the base end part 13 includes two rotary plates 9 with the base end parts 13 fixed to the slider body 7, the other end parts 14 being rotatably fixed to the door fitting tool, and an opening and closing regulator 10 where a roller 11 is journaled at the tip is connected to the base end part of one of the rotary plates. The tip roller is limited in movement by the regulating walls A and B. When a door 16 is moved in the opening direction, the tip roller of the opening and closing regulator performs circular movement along the regulating wall A, whereby the opening and closing regulator is turned and the rotary plates are turned with it, so that the tip roller of the opening and closing regulator is released from limitation on the movement due to the regulating wall A, and shifted to linear movement due to the regulating wall B, thereby the slider linearly moves. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention is a door slide rail mechanism used for a pair of left and right sliding doors of a storage such as a closet, and in particular, when the door is closed, the door is flat, and when the door is opened, the door is moved forward. The present invention relates to a door slide rail mechanism that can move laterally.

  The doors used for storage such as a closet are two doors that are fixed to the storage body with hinges etc. at the left and right ends, and the doors on both the left and right sides rotate open around the hinges. There are two types of sliding doors in which a single door moves left and right on two rails provided in parallel in the front and rear.

  In case of doors with double doors, the two doors are flat when the doors are closed, but there is a problem that a space is always required in front of the doors to open the doors. In this case, each door is slid to the left and right, so there is no need for a space in front of the door that opens the door. However, when the door is closed, the two doors are placed on the two rails. Due to the arrangement, the two doors are not flat, not aesthetically pleasing, and are inferior to double doors.

In order to solve the above-mentioned problems, several mechanisms have been proposed for sliding doors and doors that become flat when closed. As such an example, there is a sliding door device disclosed in JP-A-2005-36551.
JP 2005-36551 A

  In the slide door device disclosed in Patent Document 1, a spring or the like is used to draw the door forward, and the mechanism is complicated. In addition, many other conventional sliding door devices have complicated mechanisms and are expensive to manufacture.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-described problems and to realize a door slide rail mechanism that can realize a flat state when a sliding door is closed with a simple mechanism.

A door slide rail mechanism that can be flattened with the sliding door closed, and the slide rail and two slide tools pivotally supported on the slide rail by a plurality of rollers so as to be movable in the left-right direction. The slide rail is provided with two guide portions to which the roller can move on both side surfaces of the interior, and a straight regulation wall B and a curve connected to both ends of the regulation wall B on the interior ceiling surface. The above-mentioned slide tool is composed of a slide tool main body, a door mounting tool, and a link member that connects the slide tool main body and the door mounting tool, and the link member has a base end portion. Are attached to the slide tool main body, the two rotary plates whose other ends are rotatably attached to the door fixture, and the base end of one of the rotary plates at the distal end. Open with the roller supported A restricting tool is connected, the open / close restricting tool is rotated in conjunction with the rotation of the rotating plate, and the movement of the roller at the tip of the roller is restricted by the restricting walls A and B, and the door is opened. When moving in the direction, the roller at the tip of the opening / closing restricting tool moves circumferentially along the restricting wall A, whereby the opening / closing restricting tool is rotated, and accordingly, the rotating plate is rotated, When the roller at the tip of the opening / closing restricting tool is released from the restriction of movement by the restricting wall A and shifts to linear movement by the restricting wall B, the sliding tool can be moved linearly.

  Further, the slide rail is provided with a stopper for stopping the linear motion of the slide tool, and the linear movement of the slide tool when the door is closed is stopped by the stopper, and the roller at the tip of the opening / closing control tool is moved to the control wall. It is preferable to shift from a linear movement along B to a curved movement along the regulation wall A, and the opening / closing regulating tool and the turning plate are turned to move the door mounting tool to a predetermined door closing position.

  The opening / closing restricting tool and the rotating plate connected thereto are pivotally supported on the bottom surface of the slide tool main body so as to rotate around the same point at the base end of the rotating plate. Preferably it is.

  Further, the door mounting tool is composed of two members having a substantially L-shaped cross section, and the tip ends of the two link members are rotatably mounted on the bottom surface of one member. It is preferable that a hole for attaching the door is provided on the side surface, and the two members are fixed to each other.

  A door slide rail mechanism that can be flattened with the sliding door closed, and the slide rail and two slide tools pivotally supported on the slide rail by a plurality of rollers so as to be movable in the left-right direction. The slide rail is provided with two guide portions to which the roller can move on both side surfaces of the interior, and a straight regulation wall B and a curve connected to both ends of the regulation wall B on the interior ceiling surface. The above-mentioned slide tool is composed of a slide tool main body, a door mounting tool, and a link member that connects the slide tool main body and the door mounting tool, and the link member has a base end portion. Are attached to the slide tool main body, the two rotary plates whose other ends are rotatably attached to the door fixture, and the base end of one of the rotary plates at the distal end. Open with the roller supported A restricting tool is connected, the open / close restricting tool is rotated in conjunction with the rotation of the rotating plate, and the movement of the roller at the tip of the roller is restricted by the restricting walls A and B, and the door is opened. When moving in the direction, the roller at the tip of the opening / closing restricting tool moves circumferentially along the restricting wall A, whereby the opening / closing restricting tool is rotated, and accordingly, the rotating plate is rotated, Since the roller at the tip of the opening / closing restricting tool is released from the restriction of movement by the restricting wall A and shifts to the linear movement by the restricting wall B, the sliding tool can be moved linearly. With a simple structure, it is possible to flatten the sliding door in a closed state, it has excellent aesthetics of the door when it is closed, eliminates wasted space in front of the door, and reduces the number of parts , Production costs can be reduced And

  Further, the slide rail is provided with a stopper for stopping the linear motion of the slide tool, and the linear movement of the slide tool when the door is closed is stopped by the stopper, and the roller at the tip of the opening / closing control tool is moved to the control wall. By shifting from a linear movement along B to a curved movement along the restriction wall A, the opening / closing restricting tool and the rotating plate are rotated, and the door mounting tool moves to a predetermined door closing position. The doors can transition to a flat closed state without contacting each other.

  The opening / closing restricting tool and the rotating plate connected thereto are pivotally supported on the bottom surface of the slide tool main body so as to rotate around the same point at the base end of the rotating plate. Therefore, the door mounting tool can be moved smoothly and reliably by the opening / closing regulator and the rotating plate.

  Further, the door mounting tool is composed of two members having a substantially L-shaped cross section, and the tip ends of the two link members are rotatably mounted on the bottom surface of one member. A hole for attaching the door is provided on the side surface, and the two members are fixed to each other, so that the door can be reliably supported and slid.

  An embodiment of the door slide rail mechanism of the present invention will be described with reference to the drawings. FIG. 1 is an overall bottom view of the door slide rail mechanism 1.

  The door slide rail mechanism 1 includes a slide rail 2 shown in FIG. 2 and a slide tool 3 shown in FIG. As shown in the overall bottom view of FIG. 1, two slide tools 3 are movably attached to one slide rail 2, and one door 16 is attached to each slide tool 3. The slide tool 2 includes two rollers 11 on both side surfaces thereof, and the slide tool 3 can move the slide rail 2 in the left-right direction by the roller 11.

  As shown in the bottom view of FIG. 2, the slide rail 2 is provided with guide portions 4 for the rollers 11 to move on both inner side surfaces. In addition, a restriction wall A and a restriction wall B are provided on the ceiling surface of the slide rail 2. The restriction wall A is a curve and is connected to both ends of a straight restriction wall B. The regulation walls A and B regulate the movement of the slide tool 3, whereby the door 16 can be moved forward when the door 16 is opened.

  The slide tool 3 includes a slide tool body 7 and a door fixture 8 and a link member that connects the slide tool body 7 and the door fixture 8 (see FIG. 3). The link member includes two rotating plates 9 and one opening / closing restricting tool 10, and the sliding tool main body 7 and the door mounting tool 8 are connected by the two rotating plates 9. The rotation plate 9 is fixed to the slide tool body 7 at the base end portion 13 so as to be rotatable, and is fixed to the door attachment tool 8 at the multi-end portion 14 so as to be rotatable.

  An opening / closing restricting tool 10 that engages in rotation of the link member 9 is connected to the base end portion 13 of one of the rotation plates 9. The rotating plate 9 is fixed in a state having a predetermined angle with the base end 13 serving as the center of rotation as a center. The opening / closing restricting tool 10 has a bent shape as shown in FIG. 11, and passes through the slide tool body 7 from the bottom surface of the slide tool body 7, and its tip is located on the upper surface of the slide tool body 7. It has become. For this reason, a hole 23 is provided in the bottom surface of the slide tool main body 7 so that the opening / closing regulating tool 10 can be rotated.

  When the rotation plate 9 rotates about the base end portion 13 fixed to the slide tool body 7 so as to be rotatable, the door mounting tool 8 moves from the slide rail 2 to the front, and the door 16 is moved. Can move from one flat to the other.

  The door fixture 8 is composed of two members (5, 6) having a substantially L-shaped cross section, and the multi-end portion 14 of the rotating plate 9 is fixed to the bottom surface of the member 5 so as to be rotatable. A hole 17 for attaching the door 16 is provided on the side of the door 16, and the door 16 is attached using the hole 17. The door 16 is attached to the door slide rail mechanism 1 by the members 5 and 6 being fixed to each other.

  A roller 12 is pivotally supported at the tip of the opening / closing regulator 10 (see FIG. 13). The movement of the roller 12 within the slide rail 2 is restricted by the restriction wall A and the restriction wall B.

  The slide rail 2 is provided with a stopper 15 for stopping the movement of the slide tool in the left-right direction. When the door 16 is closed by the stopper 15, the movement of the slide tool 3 is stopped.

  Next, the operation state of the door slide rail mechanism 1 of the present invention will be described. First, the movement for opening the door 16 will be described.

  FIG. 4 shows a state in which the door 16 is closed, and the two doors 16 are flat with each other. From this state, the door 16 is moved in the opening direction (the direction of arrow A in FIG. 4). If it does so, the roller 12 provided in the front-end | tip of the opening / closing control tool 10 will carry out the circumference movement in the direction of the arrow B of FIG. While the roller 12 is moving in the circumferential direction, the sliding tool body 7 is stopped, and the opening / closing restricting tool 10 is rotated in the direction of the arrow C in FIG. The door attachment 8 is moved from the slide rail 2 to the front by rotating in the direction of the arrow D in FIG.

  When the above operation is performed and the roller 12 at the tip of the opening / closing restrictor 10 completes the circumferential movement of the arrow B along the restriction wall A5 through the state shown in FIG. 5, the movement of the roller 12 by the restriction wall A is restricted. The linear movement along the restriction wall B is enabled (see FIG. 5). The door 16 is in a parallel state with a predetermined distance from the right door 16 as shown in FIG. 5, and the left door 16 is movable in the opening direction. From this state, the door 16 is moved further to the right. When moved, the roller 12 at the tip of the opening / closing restricting tool 10 is in a state of being linearly movable along the restricting wall B, so that the rotation of the opening / closing restricting tool 10 and the link member 9 is finished, and the slide tool body 7 In addition, the entire slide tool 3 including the door mounting tool 8 can be linearly moved in the direction indicated by the arrow A.

  While the slide tool 3 is linearly moved in the direction of arrow A, the movement of the roller 12 at the tip of the opening / closing restriction tool 10 is restricted in the linear direction by the restriction wall B. Since the tool 10 cannot be rotated, the left door 16 moves while maintaining a parallel state with a predetermined distance from the right door 16, so that the doors 16 do not contact each other.

  The movement of the slide tool 3 in the opening direction ends when the two doors 16 overlap each other, and the opening of the doors 16 is completed. At this time, the left and right slide tools 3 are set to a size that does not collide with each other.

  Next, the movement from the opened state of the door 16 to the closed state will be described. Basically, the movement opposite to that when the door 16 is opened is performed.

  The door 16 is moved in the closing direction (the direction opposite to the arrow A in the figure). At this time, since the opening / closing restricting tool 10 is restricted to only the linear movement in the lateral direction by the restriction wall B, the sliding tool 3 continues to move linearly in the closing direction.

  The linear movement of the slide tool 3 is stopped by the stopper 15. At this time, the roller 12 at the tip of the opening / closing restricting tool 10 has moved to the end of the restricting wall B, where it is released from the restriction by the restricting wall B and shifts to a circumferential movement along the restricting wall A5. .

  The movement of the slide tool main body 7 is completed at this point, and the rotation of the open / close restricting tool 10 is started when the roller 12 at the tip of the open / close restricting tool 10 shifts to a circumferential movement along the restricting wall A5. The pivot plate 9 also pivots about the base end portion 13 and the door attachment 8 moves to the slide rail 2 side.

  When the movement of the door fixture 8 to the closed state of the door 16 is completed, the door 16 returns to a flat state, and the closing of the door is completed.

  As described above, the door slide rail mechanism 1 of the present invention has a simple configuration, enables the door 16 to create a flat state in the closed state, and can realize more smooth opening and closing of the door. In addition, since the configuration is simple, the number of parts can be reduced, manufacturing costs can be reduced, and assembly labor can be reduced.

  So far, the door slide rail mechanism 1 has been described, but the configuration of the slide door 20 using the door slide rail mechanism 1 of the present invention will be described.

  In the present embodiment, an embodiment in which the door slide rail mechanism 1 is used on the bottom surface of the slide door 20 will be described. In addition to this, it is also possible to use the door slide rail mechanism 1 on the upper surface or both upper and lower sides.

  FIG. 7 is an overall front view of the slide door 20. The slide door 20 includes a door slide rail mechanism 1 provided at a lower portion, two doors 16, and a frame 19 for fixing the door slide rail mechanism 1. This slide door 20 is used for a storage, a closet, or the like.

  The door slide rail mechanism 1 is attached to the lower part of the frame 19. The door slide rail mechanism 1 is fixed to the frame 19 at both ends of the slide rail 2 with the bottom surface having a gap so that the slide tool 3 can move. The lower end of the door 16 is fixed to the door slide rail mechanism 1 and the door attachment 8 of the door slide rail mechanism 1 with bolts or the like.

And the guide roller attachment 22 is attached to the upper part of the door 16, and the guide roller 21 is rotatably attached to the guide roller attachment 22 (refer FIG. 8). The guide roller 21 is movable along a groove 18 provided in the upper part of the frame 19.

  As shown in FIG. 8, the groove 18 is straight at the center and curved at both ends, and is formed so that the door 16 can be moved by the door slide rail mechanism 1.

  Since the guide roller 21 is rotatably supported by the guide roller mounting tool 22, the upper portion follows the movement of the lower portion of the door 16 when the door 16 is opened and closed by the operation of the slide rail mechanism 1. It is possible to do.

  The slide door 20 configured as described above is supported by the above-described door slide rail mechanism 1 and performs an opening / closing operation. The slide door 20 has a structure for simply guiding the movement of the door 16 at the upper part. For this reason, compared with a conventional sliding door having a complicated mechanism up and down in order to flatten the door, it becomes a simpler structure, and furthermore, a sliding door having a stable structure can be realized because it has a heavy object in the lower part. .

In addition, since the door is flat when closed, it has excellent aesthetics and can effectively use the space in front of the door.
